A local stress approach for ductile crack propagation (Integration into the GTN model framework and demonstrations)

Mechanical Engineering Journal
A local stress approach, employing failure conditions derived from notched round-bar tensile tests has successfully traced the ductile crack propagation in compact tension (CT) specimens. The failure condition is expressed using the failure stress index (
